About this network

AS-REUBENONLINE is held by Yolo Risk Management LLC of Stanhope, New Jersey. The handle and the ARIN contact both point at one person: every role on the record — technical, administrative, routing, DNS, NOC and abuse — is Alex Rubenstein at reubenonline.com. This is a personal or one-person network, not a service provider.

What it's used for

• Whatever its operator runs on it. The AS announces a single IPv4 /24, 23.162.168.0/24 (256 addresses), registered to Yolo Risk Management itself, plus one IPv6 /40, 2602:ff94::/40. Both are first-party. There is one observed neighbour.
• No reverse DNS turned up on the addresses sampled, and a sample of two proves nothing either way, so the actual workload on the space is genuinely not determined from the outside. It is not classified here rather than guessed at.

Notable

• This ASN is the clearest reissue in its neighbourhood. ARIN registered the organization in April 2025 and the AS number in July 2025 — the number is older than the holder by a quarter-century. Anyone reading AS11981 as an early-internet allocation would be wrong by decades, and the same trap is set across the whole AS11000 range.
• The tiny, tidy footprint — one /24, one /40, one upstream — is the standard shape of a personal AS: portable space, IPv6 from the start, a single transit relationship, run for the operator's own infrastructure and for the pleasure of running it.

Interesting

• The company name says nothing about the network here; the ARIN contact block is what actually identifies the operator.
